Performance Evaluation of a Preclinical SPECT Scanner with a Collimator Designed for Medium-Sized Animals

Figure 1

The overview of U-SPECT5/CT E-class. (a) The front side of the system. (b) The back side of the system. A tubular protrusion on the back side (blue arrow) can hold a 94 cm long bed for medium-sized animals. (c) Photo of bed for medium-sized animals. (d) General-purpose medium-sized animal (GP-MSA) collimator. (e) Geometric illustration of GP-MSA collimator in the two stationary detectors. The bore diameter of GP-MSA collimator is 135 mm, and the transaxial size of center field-of-view (cFOV) is 65 mm. (f) Scout view of a rabbit scanned with X-ray system combined with the SPECT system.
